This guide explains how to repair, maintain and replace your roof, what it costs, what materials work best, and how to stay compliant with UK building regulations.
Why Roof Repair and Installation Matters

Common Roof Problems in the UK
Roofs take a beating in the UK climate. Here are typical problems homeowners face:
Broken or missing tiles: Storms can lift tiles or slates.
Leaking flat roofs: Felt or rubber roofs often develop cracks or ponding.
Blocked gutters: Overflow can damage brickwork and cause damp.
Sagging roofs: Structural issues with rafters or beams.
Moss or debris: Can trap moisture and speed up wear.
Roof Repair – What You Need to Know
Minor Repairs:
Replacing a few tiles, patching a flat roof, re-pointing chimney stacks.
Moderate Repairs:
Replacing lead flashing around chimneys or dormers, repairing rotten timbers, resealing joints.
Major Repairs:
Re-roofing a section or the whole roof, installing new underlay, upgrading insulation.
Tip: Spot small issues early! An annual roof check can prevent expensive repairs later.
Roof Installation – Options for 2025
